Hi All,
I am an IT engineer, and I use to help others to do thing better and simple.
Well, in fact, Windows Photo Viewer is available on all Windows 10 including 21H2 and on Windows 11, too. The main problem, that it is hidden, and cannot be chosen from Open With context menu.
To achieve this I would recommend to read the following article. It is really nice and a good way to get the WPV back on your Windows whichever version you had.
After you do as per instruction below, click on the photo. You will see a pop-up window to choose what app to open the photo with. And voila, you will see WPV among others apps.
I hope this will help to save pretty much time while looking through your photos.
